Remember kindness is free.

I think this explains why some of my friends back in college who did extreme weight lifting complains having problems to build muscles, even though proper diet, nutrition and targeted muscle group workout were incorporated.

And there’s that one guy they knew that never been (or at least tried couple times) swimming, played soccer or do weight lifting, but surprisingly has quite physique of an athlete.

Our body is really a magical matter.
